Answer 1

We are currently working on a project which uses both Hibernate and ibatis. Why use hibernate ? It supports our domain model, relationships and inheritance. We have a pretty complex domain model and hiberante supports it very well. No need to worry about writing inserts, updates etc. Ibatis is used only for view. There are queries and we have view objects(similar to domain models but not domain models) which are mapped with queries. Ibatis returns the data in the view obejct you want without worrying about reading from result set , which you have to manage in Spring JDBC. Why do we that instead of using HQl or Spring JDBC ? The domain is so complex and when rendering view , we do calculations , group by and tons of native SQL functions. we do all that in query, use dynamic queries , manage conditions in ibatis and get a clean light weight object. Makes much more sense if you have to traverse down multiple layers to fetch data in hibernate So depending on your situation , you may want to use only one, both or may be none. But definitely, hibernate is not something you cannot live without.
